The present invention is provided with: a loading error amount estimation unit that estimates the error amount of the load capacity of a car on the basis of the load capacity of the car and the vibration amount detected by a vibration detection sensor when a hoist is started; a resonant frequency derivation unit that derives the resonant frequency of the car; and a spring constant estimation unit that estimates the deterioration state of the anti-vibration rubber by calculating the spring constant of the anti-vibration rubber provided in the car on the basis of the vibration amount detected by the vibration detection sensor, the error amount of the load amount estimated by the load error amount estimation unit, and the resonance frequency derived by the resonance frequency derivation unit. As a result, it is possible to grasp the deterioration state of the anti-vibration rubber, thereby keeping the riding experience constant.
具备:装载误差量推定部,其根据轿厢的载重量和启动曳引机时的振动检测传感器检测到的振动量来推定轿厢的载重量的误差量;谐振频率导出部,其导出轿厢的谐振频率;和弹簧常数推定部,其基于振动检测传感器检测到的振动量、装载误差量推定部所推定的载重量的误差量、和谐振频率导出部所导出的谐振频率来算出设置于轿厢的防振橡胶的弹簧常数,从而推定防振橡胶的劣化状况。由此,能掌握防振橡胶的劣化状况,从而将乘坐体验保持恒定。
